Echo TR ISIS Cranks

Description and materials
- Popular Echo TR ISIS cranks, specifically designed for Biketrials by Asian manufacturer Echo.
- Designed with superior strength and stiffness, with a tough rib at the back of the arm, which makes these cranks reliable and durable.
- Mechanized from a single piece of high-quality 6061-T6 aluminium alloy.
- Suitable for all ISIS bottom brackets.
- CNC mechanized standard 1.37”x 24tpi thread, suitable for most screw-on freewheels and sprockets.
- Wide threaded section (13mm) to be able to run a bashring together with the freewheel/sprocket..
- Large recesses at the front of the arms help save unnecessary weight without compromising overall strength.
- Note: these cranks are supplied with a 5mm spacer that must be inserted between the freewheel and crank in case you don't use a bashring.
- Available in sand blasted black only, with grey laser etched Echo logo at the back of the arm.
- Available in 160 or 170mm.

Additional information
- Please bear in mind that there must be at least 7mm of thread in contact between freewheel and crank. Furthermore, a 1.37” freewheel/sprocket must be used with a maximum internal diameter of 33.8mm (and not the 1.375” ones). Not following these instructions may lead to thread damage (which won’t be covered under warranty).
